Benefits

Rafay's Ray as a Service offering is designed to be used by multiple users (i.e. data scientists or researchers) concurrently on the same host Kubernetes cluster. Deploying KubeRay inside a virtual cluster (aka vcluster) operating on a host Kubernetes cluster allows organizations to deliver isolated, multi-tenant environments to data scientists and researchers that they can use for running Ray workloads within a shared Kubernetes infrastructure. This is extremely useful especially when supporting multiple users/teams that require Ray.

Isolation

Each team can have its own virtual Kubernetes cluster with dedicated KubeRay operators, ensuring that workloads are isolated and do not interfere with each other. As you can see from the design above, every user/team gets access to a dedicated and isolated virtual cluster with the kubeRay operator deployed inside it.

Ray as a Service

Customized Configurations

Different teams can run different versions or configurations of Kubernetes, KubeRay, or Ray without affecting the host cluster or other teams’ environments.

Resource Management

Administrators can allocate specific resources (CPU, memory, storage) to each vcluster, enabling better control over resource consumption and preventing any single tenant from monopolizing cluster resources.

Test & Development

Users can spin up vclusters for testing new features, configurations, or upgrades in a sand boxed environment that mimics production settings without risking stability.

Collisions & Conflicts

Running multiple KubeRay operators in the same cluster can lead to conflicts. Using vclusters ensures that operators are scoped to their virtual clusters, preventing such issues.
